How Installing Energy-Efficient Windows in South Beloit Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $302 annually on your energy bills in South Beloit.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in South Beloit
Each window installation company provides varying services and has different prices depending on several factors.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200. These numbers vary depending on specific characteristics of your installation, including the location of your home, size, material, type, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save South Beloit homeowners $302+ per year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step of a window installation is to think about whether you want a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which type of installation you need, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in South Beloit
EcoWatch reviews are different from other reviews since we assess these companies through a sustainability lens. We've decided to evaluate the best window replacement companies in South Beloit primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve South Beloit so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to South Beloit's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of South Beloit window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
South Beloit, IL Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or skills, we recommend hiring a professional.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation harder.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
